We investigate the problem of decoupling capacitance allocation for power supply noise suppression at floorplan level. First, we assume that a floorplan is given, and consider the decoupling capacitance placement as a post-floorplan step. Second, we consider the decoupling capacitance placement as an integral part of a floorplanning methodology (noise aware(More)
Power supply noise is strong function of the switching activities of the circuit modules. Peak power supply noise can be significantly reduced by judiciously arranging the modules based on their spatial correlations in the floorplan. In this paper, power supply noise is, for the first time, incorporated into the cost function to determine the optimal(More)
We investigate the problem of decoupling capacitance allocation for power supply noise suppression at floorplan level. Decoupling capacitance budgets for the circuit modules are calculated based on the power supply noise estimates. A linear programming technique is used to maximize the allocation of the existing white space in the floorplan for the(More)
In this paper; we propose an event-driven simulation based approach to estimate the worst case I R drop and Ldildt inductive noise on the power supply network. The switching noise is modeled as a weighted sum of the switching currents and the rates of change of the switching currents , where the weights are respectively the effective resistance and(More)
In this paper, we propose an approach for the analysis of power supply noise in the frequency domain for <i>power/ground</i> (P/G) networks of tree topologies. We model the P/G network as a linear time invariant (LTI) pseudo-distributed <i>RLC</i> network and the gates (or cells) as time-varying current sources. Voltage fluctuation caused by the switching(More)
